I have been using M20 for one year, three months. And I am having so much internet problem. In 4G connection, The symbol shows, but only the arrow UP is constantly lit. The DOWN arrow is blank. I can't use internet for few moments. It happens constantly. I can't even watch a 5 minutes YouTube video without interruption. I went to the customer service, they couldn't found any problem. I swapped sim. Didn't work. I tested my sim in Samsung M21. It was working fine. It just happens on my M20. Galaxy Tab A. I have reset, factory data rest too. Didn't work. I updated every updates. No result. So many people is having this problem. Samsung should look into it.
